BIOTREATMENT OF MINEWATER-CONTAINING CYANIDES BY USING IMMOBILIZED CELL TECHNOLOGY

摘要: Cyanide is a metabolic inhibitor and used in large quantities mining processes. Bacteria can degrade detoxify these contaminants through normal cellular metabolism. Further, the application of immobilized cell technology industrial waste treatment offers possibility degrading higher concentrations toxic pollutants compared to free cells. In this study Pseudomonas putida pseudoalcaligenes, capable utilizing cyanide as carbon nitrogen sources were calcium alginate form beads rate degradation cyanide. Degradation potassium (KCN) ammonia (NH3) dioxide (CO2) by cells P. pseudoalcaligeneswas studied at pH 6.5 9.5. Both cultures able KCN effectively The transformation cyanides present minewater NH3 CO2 was also investigated. metals analysis showed that calcium-alginate pseudoalcaligenes remove (Cu, P, Zn, As, Co) except Pb. thus concludes (a) both NH3; (b) exhibited different rates (c) from sample.
